UC2844A, UC2842A HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER

UC2844A Description

UC284XA UC384XA HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER NOT FOR NEW DESIGN 1 .
PThe UC384xA family of control ICs provides the necessary features to implement off-line or DC to teDC fixed frequency current mode control schemes le.

UC2844A Features

* Figure 1. Package
* TRIMMED OSCILLATOR DISCHARGE CURRENT
* CURRENT MODE OPERATION TO 500kHz AUTOMATIC FEED FORWARD COMPENSATION DIP-8 SO-8
* LATCHING PWM FOR CYCLE-BY-CYCLE CURRENT LIMITING Table 1. Order Codes
* INTERNALLY TRIMMED REFERENCE WITH Part Number Package UNDE

UC2844A Applications

* The corresponding thresholds for the UC3843A and UC3845A are 8.5 V and 7.9V. The UC3842A and UC3843A can operate to duty cycles approaching 100%. A range of the zero to < 50 % is obtained by the UC3844A and UC3845A by the addition of an internal toggle flip flop which blanks the output off every oth
